You have added a new storage array into VPLEX, but it does not see it. Which VPLEX command
will display the new storage array?
A.
vplexcli./clusters/cluster-<Cluster ID>/storage-elements/storage-arrays/array re-discover
B.
vplexcli:/array claim -s
C.
vplexcli:/clusters/cluster-<Cluster ID>//storage-elements/storage-arrays>array used-by-array
D.
vplexcli:/connectivity validate-be
Explanation:
D. vplexcli:/connectivity validate-be

I have a feeling its A.
Can someone back me up on this?
Array re-discover will list the array on VPlex if the zoning is correct.

Correct answer is ‘A’. Trust me, I’m an expert on this.

Seems that A is correct.
vplexcli:/connectivity validate-be = Checks that the back-end connectivity is correctly configured (CLI Guide):
Description This provides a summary analysis of the back-end connectivity information displayed byconnectivity director if connectivity director was executed for every director in the system.
It checks the following:
◆ All directors see the same set of storage volumes.
◆ All directors have at least two paths to each storage-volume.
◆ The number of active paths from each director to a storage volume does not exceed 4.
array re-discover = Re-discovers an array, and makes the array’s storage volumes visible to the VPLEX (CLI Guide):
Description Manually synchronizes the export state of the target device. Used in two scenarios:
◆ When the exported LUNs from the target array to VPLEX are modified.
Newer protocol-compliant SCSI devices return a notification code when the exported
set changes, and may not require manual synchronization. Older devices that do not
return a notification, must be manually synchronized.
◆ When the array is not experiencing I/O (the transport interface is idle), there is no
mechanism by which to collect the notification code. In this scenario, do one of the
following:
• Wait until I/O is attempted on any of the LUNs,
• Disruptively disconnect and reconnect the array, or
• Use the array rediscover command.
array used-by = Displays the components that use a specified storage-array (CLI Guide):
Description Displays the components (storage-volumes) that use the specified storage array.
connectivity validate-be = Checks that the back-end connectivity is correctly configured (CLI Guide):
Description This provides a summary analysis of the back-end connectivity information displayed by
connectivity director if connectivity director was executed for every director in the system.
It checks the following:
◆ All directors see the same set of storage volumes.
◆ All directors have at least two paths to each storage-volume.
◆ The number of active paths from each director to a storage volume does not exceed 4.
